Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hot-melt kettles for sealing glue, in particular to a novel hot-melt kettle for sealing glue. Background Art
[0002] The hot melt kettle for potting glue is a kind of equipment specially used for heating and melting pavement potting glue. This equipment adopts indirect heating method, uses diesel as fuel, and heats through heat transfer oil as heat medium. It has the advantages of safe heating, precise temperature control and gentle heating process.
[0003] During the design and manufacturing process, firstly, due to the small capacity of the hot melt kettle, it is difficult to arrange enough heat exchange area for the equipment to adapt to the heating fire tube. In the limited space, it is often difficult for designers to fully consider the thermal efficiency of the equipment, so the fire tube is often designed with a relatively simple U-shaped structure. Although this structure is easy to manufacture and install, it has obvious deficiencies in heat transfer and distribution, which affects the thermal efficiency to a certain extent and leads to a higher exhaust temperature.
[0004] Further analysis shows that the reason for the low thermal efficiency is that the design of the U-shaped fire tube cannot effectively and evenly transfer heat to the caulking glue, resulting in a large amount of heat loss during the transfer process, which not only increases energy consumption, but also increases the operating cost of the equipment. At the same time, due to insufficient heat transfer, the exhaust temperature is high, which not only increases the burden on the environment, but also affects the environmental performance of the equipment.
[0005] In addition, the melting and heating process of the caulking glue is also relatively difficult. Usually, the caulking glue needs to be heated in advance so that it can be melted and used at one time. However, due to the low thermal efficiency of the hot melt kettle, the amount of caulking glue used per day is limited and continuous operation cannot be achieved. This not only reduces the daily use effectiveness of the equipment, but also increases the production cycle, affecting production efficiency.
[0006] In summary, the existing new hot melt kettle for potting glue has obvious deficiencies in thermal efficiency, heating uniformity and melting efficiency. The existence of these problems not only affects the performance of the equipment, but also limits its efficiency and practicality in practical applications. Therefore, a new hot melt kettle for potting glue is needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION
[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0025] See also Figure 1-3The utility model provides a technical solution: a new type of hot melt kettle for potting glue, comprising a heating fire tube 1, a heat transfer oil chamber 2, a stirrer 5 and a heating stirring tank 12, wherein the heating fire tube 1 is installed in the middle of the heat transfer oil chamber 2 below the heating stirring tank 12, and a heating stirring tank 12 for melting glue is installed on the side of the heat transfer oil chamber 2 away from the ground.
[0026] This embodiment is a structure for increasing the heat exchange area, optimizing smoke convection, improving the thermal efficiency of the fire tube and enhancing the working efficiency of the hot melt kettle.
[0027] It should be noted that the heating fire tube 1 is serpentine, and a burner mounting tube 8 is fixedly installed at one end of the heating fire tube 1. A fire tube radiation zone 11 is opened in the heating fire tube 1. A plurality of evenly distributed welded small tubes 10 are installed in the convection zone in the middle of the heating fire tube 1 to improve the internal flue gas heating effect. A smoke exhaust pipe 9 is fixedly connected to the other end of the heating fire tube 1. The heating fire tube 1 maximizes the heat exchange area in a limited space and adopts a structural design that reduces the smoke resistance, thereby effectively improving the thermal efficiency.
[0028] It is understandable that a feeding port 4 is fixedly installed on the side of the heating and stirring tank 12 away from the ground, and a rubber melting tank 3 located below the feeding port 4 is fixedly installed on the inner wall of the heating and stirring tank 12 to facilitate adding raw materials therein.
[0029] In addition, a stirring and heating zone 6 is provided inside the heating and stirring tank 12 for the stirrer 5 to heat and stir the rubber material, so as to continuously heat and stir the rubber material and ensure that the rubber material operates at a high temperature in a liquid state.
[0030] In this embodiment, a plurality of evenly distributed welding fins 7 are fixedly installed on the inner wall of the glue melting tank 3. When heated, the glue block is heated and melted by the high-temperature welding fins 7, and the melted glue continuously flows into the heating and stirring zone 6 on the right. When in use, the glue in the heating and stirring zone 6 is in a liquid high-temperature state, and the agitator 5 is always stirring. The newly added glue block is in the glue melting tank 3 and does not affect the continuous stirring of the agitator 5. In this way, the melted glue and the potting glue can be discharged and used simultaneously during the grouting operation, which improves the operating capacity of the equipment and also reduces the energy consumption of heating and heat preservation of the glue.
[0031] It should also be noted that the burner mounting tube 8 and the fire tube radiation zone 11 cooperate with each other to drive the heat transfer to the welded small tube 10, which is convenient for burner installation and flue gas radiation, helps the transfer and distribution of heat, and also improves the flue gas heating effect. These welded small tubes 10 help the flue gas to convect in the fire tube, thereby improving the thermal efficiency.
[0032] The working principle of the above embodiment is:
[0033] The heating fire tube 1 adopts a serpentine tube design, which increases the effective length of the fire tube, thereby increasing the heat exchange area, which helps to improve thermal efficiency, make heat distribution more uniform, and reduce local overheating. The burner mounting tube 8 and the fire tube radiation zone 11 cooperate with each other to heat the rubber material by radiation heat. The welded small tube 10 added to the middle convection zone of the heating fire tube 1 improves flue gas convection and improves the heating effect. Multiple welded small tubes 10 help flue gas flow in the fire tube, reducing flue gas resistance and making heat transfer more efficient. The exhaust pipe 9 is used to discharge the flue gas generated during the combustion process to keep the heating kettle clean and safe. Below the feeding port 4 is the rubber melting tank 3, which is where the rubber material begins to melt. The rubber block begins to melt under the enhanced heating of the welding fins 7, and the melted rubber will flow into In the stirring and heating zone 6, the agitator 5 will continue to stir the rubber material to ensure that the rubber material is evenly heated and prevent local overheating. The rubber material in the stirring and heating zone 6 always remains in a liquid high-temperature state to ensure that the newly added rubber block can melt quickly and does not affect the continuous stirring of the agitator 5. When new rubber blocks need to be added, the rubber blocks in the melting zone of the new blocks will be added to the rubber melting tank 3 and melted quickly under the action of the welding fins 7. Since the agitator 5 is always stirring, the newly added rubber blocks can be quickly mixed with the liquid high-temperature rubber after melting in the rubber melting tank 3. During the grouting operation, the molten rubber and the potting glue can be discharged and used simultaneously, which improves the working efficiency of the hot melt kettle, reduces the time waiting for the rubber material to melt, and can operate continuously, thereby reducing energy consumption and improving the overall operating capacity.
[0034] Compared with the prior art: the new type of potting glue hot melt kettle, through the mutual cooperation of the heat transfer oil chamber 2, the glue melting tank 3, the feeding port 4, the stirrer 5, the stirring heating zone 6, the welding fin 7, the burner installation tube 8, the exhaust pipe 9, the welding small tube 10, the fire tube radiation zone 11 and the heating stirring tank 12 on the heating fire tube 1, can provide a complex serpentine tube design, significantly increase the heat exchange area, not only optimize the smoke convection, but also improve the thermal efficiency of the fire tube, so that the fire tube heating area is greatly improved, thereby enhancing the working efficiency of the hot melt kettle, inside the hot melt kettle, the glue stirring zone and the new block material are specially designed The addition of the melting zone not only improves the working efficiency of the hot melt kettle, but also significantly improves the thermal efficiency of the hot melt kettle, and ensures that the hot melt kettle can complete its work more efficiently, thereby achieving effective utilization of energy and cost reduction in the production process. At the same time, during the construction process, new glue blocks can be continuously added, which significantly improves the daily working capacity of the equipment and can respond more flexibly to changes in production needs. While ensuring production efficiency, it also improves the flexibility and adaptability of the production line, solving the problems of low thermal efficiency and insufficient heat transfer of existing potting glue hot melt kettles, which affect environmental protection performance and production efficiency.
